Application tiled .Tune 22, 1909. Serial No. 503,610.

considerable skill and patience to assemble,

to furnish a device which constitutes a perplexing and indirect puzzle or toy for testing the ingenuity; and to provide a block puzzle consisting of a plurality of blocks, which when assembled present a structure having lines of separation not easily detected, thereby increasing the ditliculty experienced in disassembling the structural elements of the puzzle after the latter has been set up.

The invention will be hereinafter considered in detail and then claimed, and reference will nowfbe hadA to the drawing forming land Fig. 2 is a similar view of one of the inner apart of this specification, wherein there is illustrated a preferred embodiment of the invention, but it is to be understood that the structuralelements thereof can be varied, as to the size, shape and manner of assemblage without departing from the spirit of the invention.

lathe-drawings: Figure 1 is an elevation plan of one of the foundation blocks,

blocks, Fig. 3 is a similar view of the locking blocks, Fig. 4 is a similarl view of another inner bloek, Fig. 5 is a similar view of the tie block, Fig. 6 is a perspective view of another of the foundation blocks, FiO'. 7 is a similar view of the two foundationilocks when assembled, Fig. 8 is a similar view of the foundation blocks, and one of the inner blocks assembled, Fig. 9 is a similar view showing the locking block added to the structure shown in Fig. 8, Fig. 10 is a perspective view showing the inner blocks, the foundation blocks, and the locking block assembled,

and Fig. 1l is a perspective View showing the various blocks of the puzzle 1n an assembled osition.

Referring to the drawings in detail, 1 denotes a rectangular foundatlon block, which and l5, the grooves groove 2 is of greater width than the groove 3 and the groove 4 is ofgreater Width than the groove 5, the said grooves 4 and 5 intersecting the grooves 2, 3 and the said two pairs of grooves provide what may be grooves 2 and 3 and a pait-` disposed at right angles with' termed an intermediate web 6 at one sidev of the center of the block in the direction of its length. The remaining portion of the body of the block 1 after the grooves 2, 4, have been provided is termed a shank and is indicated by the reference character 9. The reference character 7 denotes another rectangular foundation block which is provided in one side with a transverse groove 8 to receive the shank 9 of the block 1 and so that the said block 7 can be seated in the grooves 2 and 1. The block 7 is provided with a transverse groove 11 in the side there of and which is disposed at right angles with respect to the groove 8 and is of greater width than said groove 8 and the said block 7 is furthermore provided with a groove 10 of less length than the groove 8 but said groove 10 extends in parallelism with respect to the groove 8 and intersects the groove 11.

The reference character 12 indicates one of the inner blocks and which is provided in one side with a` transverse groove 13 and in another side with a transverse groove 14;, the groove 13 intersecting the groove 14 and disposed at right angles with respectl thereto and the said groove 14 is adapted to receive the web 6' and the grooves 13, a portion of the foundation block 7 being clearly Shown in Fig. 8.'

The reference character 15 indicates a locking block which is provided with a transverse groove 16 and a transverse groove 18 upon the saine side of the block, the groove tti being of greater length than the groove 18 and the said block 'in the side at right angles to the side in which the grooves 16 and 18 are provided is formed with `a longitudinally t-xtem'li11g groove 17 opening into the groove 1.(3 and intersected by a transversely extending groove 19 which is intersected by the groove 18. The groove 16 is adapted to receive a portion of the block 7 1 and when the said block 15 receives a porthe block is in one side with a transverse groove 2l and in v another side with a transverse groove 22 which intersects the groove 21 and 1s d15- posed at right angles with respect to said -groove 21. The block 20- when seated in position and as shown in Fig. 10 is mounted in the roove '19 and in a part. of the groove 17 of t e locking block 15.

The reference character 23 indicates the tie block and which is provided with a transverse groove 24 in one side and With a pair of transverse grooves 25 and 26 in another side, the grooves 25 and 26 providing a tongue 27 and intersecting the groove 24 and disposed at right .angles With respect to said groove 24. When the tie lblock 23 is .seated in position, the groove 24 is adaptedl to receive the inner blocks 12 and 20 as clearly shown in Fig. 11 and the grooves -25 and 26 are adapted to receive the blocks l and 15 and when the tie block 23 is in position, the tongue 27 extends between the blocks 1 and 15.

'A distinguishing feature of the puzzle is that the foundation block 1 and the locking block 15 provide an opening or a socket to receive the tongue 27 carried by the tie bar.

`When the puzzle is set up, the separable or division lines of the blocks present practically the same appearance upon one side of the device as the other, see Fig. 11, and therefore it is a difiicult matter to determine the first block to be moved when it is desired to disassemble the puzzle and also that it is very perplexing when the puzzle is disassembled to select the foundation or4 building block when it is desirable to assemble the block.

shown in Fig. 4. Whenv Having now described my invention what A puzzle com rising foundation blocks, a tie block, -inner locks, and a locking block, each of said blocks being of the same length and cross-sectional area, one of said foundation blocks provided with intersecting transverse grooves forming said blocks with a web and a shank, and the other of said foundation blocks having transverse grooves in one side and a transverse groovein another side approximately three times the Width of one of the other grooves of said block and said 'last mentioned groove receiving said shank, one of said inner blocks having transverse grooves disposed at right angles, one of Wnich receives said 'web and the other of which receives a part of the second foundation block, having a transverse groove for the reception of said second foundation block and further having a transverse groove alining with one of the transverse grooves of the rst foundation block, and said locking block further provided in oneside Witha longitudinally extending groove and a transverse groove intersecting the longitudinal groove, the other of said inner blocks provided with transverse grooves disposed at right angles and intersecting each other for receiving said locking block, and said tie member pro` vided With a .pair of transverse grooves forming a tongue and further having a transverse groove at right angles With rcspect to the pair of grooves and receiving said inner blocks, said pair of grooves receiving said first foundationblock and the locking block, and said tongue' extending between the last mentioned blocks'. 1

In testimony whereof I aiiX my signature l in the presence of tivo Witnesses.
